-#
-# = open3.rb: Popen, but with stderr, too
-#
-# Author:: Yukihiro Matsumoto
-# Documentation:: Konrad Meyer
-#
-# Open3 gives you access to stdin, stdout, and stderr when running other
-# programs.
-#
-
-#
-# Open3 grants you access to stdin, stdout, stderr and a thread to wait the
-# child process when running another program.
-#
-# Example:
-#
-#   require "open3"
-#   include Open3
-#   
-#   stdin, stdout, stderr, wait_thr = popen3('nroff -man')
-#
-# Open3.popen3 can also take a block which will receive stdin, stdout,
-# stderr and wait_thr as parameters.
-# This ensures stdin, stdout and stderr are closed and
-# the process is terminated once the block exits.
-#
-# Example:
-#
-#   require "open3"
-#
-#   Open3.popen3('nroff -man') { |stdin, stdout, stderr, wait_thr| ... }
-#

-module Open3
-  # 
-  # Open stdin, stdout, and stderr streams and start external executable.
-  # In addition, a thread for waiting the started process is noticed.
-  # The thread has a thread variable :pid which is the pid of the started
-  # process.
-  #
-  # Non-block form:
-  #   
-  #   stdin, stdout, stderr, wait_thr = Open3.popen3(cmd)
-  #   pid = wait_thr[:pid]  # pid of the started process.
-  #   ...
-  #   stdin.close  # stdin, stdout and stderr should be closed in this form.
-  #   stdout.close
-  #   stderr.close
-  #   exit_status = wait_thr.value  # Process::Status object returned.
-  #
-  # Block form:
-  #
-  #   Open3.popen3(cmd) { |stdin, stdout, stderr, wait_thr| ... }
-  #
-  # The parameter +cmd+ is passed directly to Kernel#spawn.
-  #
-  # wait_thr.value waits the termination of the process.
-  # The block form also waits the process when it returns.
-  #
-  # Closing stdin, stdout and stderr does not wait the process.
